well, i have a OO terrier, which was one of the first OO released in the GWR button livery way back when by Dapol
i had started to modify the shell to ex IOW it, but Dapol bought out the O gauge version, so i have abandoned my Terrier, in pieces, and have a nice collection of 4 O gauge ones.
However, should decent new versions come out in OO, then i would snaffle them up. I love Terriers
